PIVOTAL SUPPORT FOR MIRRORS.

SFECIFICATIOIT forming part of Letters Patent No. 34%,854, dated July 6,1886.

Application filed August 28, 1853. Serial No. 104,987. (No model.)

To aZZ whom it may concern:

Be it known that I, J osnrrr PENNEY, of Grand Rapids, in the county ofKent and State of Michigan, have invented a new and Improved PivotalSupport for the Mirrors of Dressing-Cases, &c., of which the followingis a specification.

My invention has reference to those mirrors which are supported atopposite sides on horizontal pivots, to the end that they may be tippedor tilted in a vertical plane to vary their inclination.

It is the aim of the invention to produce a device which may beconstructed at small cost, and which may be applied with less labor thanthose now in common use, and which shall at the same time serve to holdthe mirror-supporting standards in their proper position, and to holdthe mirror in the inclination or position at which it may be adjusted.

With these ends in view I make use of a trunnion or pivot adapted at oneend to be driven into a hole in the frame of the mirror, and adapted atits opposite end to be seated in an opening of such form that it may bereadily cut in the standard by machine tools, and in connection withthis pivot employ a fastening-plate adapted for attachment to thestandard by a single screw, one end being suitably formed to enter arecess in the standard and bear upon the trunnion therein, so as toserve the double purpose of confining the trunnion in place and ofsubjecting the same to a friction sufficient to prevent its accidentalrotation.

In the drawings, Figure 1 represents a rear elevation of a portion of amirror-frame and its supporting-standard connected by my improveddevice. Fig. 2 is a horizontal section on the line 00 x of Fig. 1. Fig.3 is a perspective view of the fasteningplate. Fig. 4 is a perspectiveview of a portion of the frame, showing a recess thereunder to receive apivot or trunnion.

Referring to the drawings, A represents one of the standards forsupporting the mirror, and B a portion of the mirror-frame plate securedto the frame by a screw, (l,- and D, the pivot or trunnion.

shank, a, of a cylindrical or other suitable form, adapted to be driveninto the standard at one end, with an enlarged flange or collar, 1), atthe middle, and with a head or enlargement, 0, preferably of a conicalform, at the opposite end. This pin is driven tightly to its place inthe standard, so as to prevent its rotation therein, its inward motionbeing limited by the collar b coming in contact with the edge of thestandard. In the inner edge of the frame which is to receive the pivot Iform in the rear side a recess, m, of a shape corresponding with that ofthe head 0. This opening may be conveniently and quickly formed by acuttingtool having an outline identical with that of the head of thepin. In assembling the parts the head of the pin is slipped horizontallyinto this opening from the rear.

The plate 0 has at one end a projection, E, adapted to enter the openingat of the frame and bear against the rear side of the pivothead, asshown in Fig. 2, in order to hold the same snugly to its place. Theplate 0 is extended laterally beyond this projection iua form suitableto bear against the rear face of the frame, and is preferably providedat its end with a lip or projection, f, by which its face is held out ofcontact with the frame. Midway of its length, or thcreabout, it is provided with a hole, 9, through which to insert the confining-screw d.

It will be observed that the plate bears at one end upon the frame, andat the opposite end on the pivot, so that the intermediate screw servesthe twofold purpose of holding the plate in place and of adjusting itwith more or less pressure upon the pivot. It will also be observed thatthe collar 1) serves to maintain the proper separation between thestandard and frame,that they may not come in contact with each other,while the enlarged head serves to tie the standard and frame together,in order to prevent their lateral separation.

I am aware that a plate provided with two holes for fasteningscrews, andwith a hemispherical projection, has been combined with two metallicclamping-plates connected by a hinge-joint and an adjusting-screw, oneof these plates being also provided with plates IOC to receive twofastening-screws, and to such construction I lay no claim.

My construction is advantageous by reason of its small cost, the factthat the mirror and standard may be fitted to receive it by means ofpower-driven tools, and the fact that the parts may be adjusted in anexceedingly short space of time.

It is to be observed that under my construction aseat for the pivot isformed in the wooden frame without the employment of a special socket,and that all the parts of the device are of such form that they-may becast and applied to use without being fitted, machined, or finished inany manner.

The confinement of the pivot against the wood is advantageous in thatayielding or elastic pressure is applied, holding the pin secure- 1y,but permitting it to revolve when moderate strain is applied. It alsoavoids the necessity of giving the pivot that smooth and accurate finishwhich would be necessary were it clamped between two metal platesconfined by a connecting-screw.

While I have described the pivot-pin as being secured to the standardwhich supports the mirror-frame, it is obvious that it may be secured tothe frame and the socket formed in the standard, this reversal ortransposition of the partsin no wise affecting their mode of action.

Having thus described my invention, what I claim is- 1. In combinationwith the standard and the pivot pin secured thereto, the mirrorframerecessed to form a direct bearing for the pivot-head, theconfining-plate bearing upon the frame and the pivot, and the screwapplied to hold the plate in position on the frame in frictional contactwith the pivot.

2. A device for suspending mirrors from their supporting-standards,consisting, first, of the pivot-pin having the stem or shank adapted forinsertion ina hole in the mirror and an enlarged head, and, second, ofthe frictional plate provided at one end with the stud or projection tobear on the pivot-pin, and near the middle with an opening to receivethe fastening-screw.

3. The improved mirror-pivot having the shank to enter the mirror-frame,the flange or collar to separate the frame and standard, and theenlarged head to co-operate with a fastening device.

4. In combination with the supportingstandard and the pivot with anenlarged head seated at one end therein, the recessed mirrorframehavingthe pivoted head seated directly in its recess, the plate seated on themirror and bearing on the pivot, and the confiningscrew passing throughthe plate into the mirror.

5. In combination with a wooden mirror- JOSEPH PENNEY.
